Battling a bum hamstring, Vikings receiver Adam Thielen played on Sunday against the Chiefs, but it was an abbreviated appearance of only seven snaps.
It's doubtful that will happen again.
Thielen is unlikely to play this Sunday against the Cowboys, NFL Network's Tom Pelissero reported Tuesday afternoon.
In addition, Pelissero explained Thielen's strained hamstring suffered no further damage against the Chiefs, but he could feel it pulling and needed to "calm it down."
